Note
The RPM4-E-DWT date and time are set to United States
Mountain Standard Time in the final test and inspection process
at the factory. If desired, use the TIME and DATE function to set
your local time and date.
3.9.5.4 <4id>
 PURPOSE
To view or edit the RPM4-E-DWT user ID and to view the RPM4-E-DWT serial
number.
 OPERATION
To access the ID function press [SPECIAL] , <5prefs> , <4ID> .
Select <1view> to view the current ID.
Select <2edit> to edit the ID.
The ID has twelve characters. When the edit screen is opened, the cursor is on
the first character. Numerical values can be entered directly from the keypad. In
addition, the cursor control keys can be used to toggle through a list of available
alphanumeric characters. Holding the key slews through the characters.
Character order going up is: blank space, symbols, lower case letters, upper
case letters, and numbers. After selecting a character, press
[ENT] to activate it
and move to the next character field.
When a character is selected the cursor moves to the next character. To leave a
blank character, press
[ENT] with the field for that character blank. Use this for
the trailing characters if the ID being entered is less than twelve characters.
After the last of the twelve characters has been entered, the <Save ID?> option
is offered. Select <1no> to return to the ID edit screen. Select <2yes> to save the
edited ID.
Note
The ID can be set remotely from a computer which is quite a bit
more convenient than entering characters from the keyboard
(see Section 4.4.4, “ID” command). The ID is not cleared or
reset by any RESET function (see Section 3.9.9).
3.9.5.5 <5LEVEL> (Security)
 PURPOSE
To set user protection levels to restrict access to certain functions and to edit the
password required for changing user levels.

PRINCIPLE
RPM4-E-DWT’s front panel user interface provides the means to access all
RPM4-E-DWT user defined data, settings and functions including calibration data.
Inadvertent, uninformed or unauthorized altering or deleting of data, settings and
functions could require extensive reconfiguration by the user and might cause invalid
readings and behavior. For these reasons, depending upon the application in which
RPM4-E-DWT is being used, it may be desirable to restrict access to some
functions. The user level function provides a means of restricting access to certain
functions. Four different levels of security are available.
Access to changing security levels can be left open, or be protected by a
password.
